Section (2) inotify_init
Name
inotify_init, inotify_init1 — initialize an inotify instance
Synopsis
#include <sys/inotify.h>
int
inotify_init( |
void) ; |
int
inotify_init1( |
int flags) ; |
DESCRIPTION
For an overview of the inotify API, see inotify(7).
inotify_init
() initializes a
new inotify instance and returns a file descriptor associated
with a new inotify event queue.
If flags
is 0,
then inotify_init1
() is the
same as inotify_init
(). The
following values can be bitwise ORed in flags
to obtain different
behavior:
IN_NONBLOCK
-
Set the
O_NONBLOCK
file status flag on the open file description (see open(2)) referred to by the new file descriptor. Using this flag saves extra calls to fcntl(2) to achieve the same result. IN_CLOEXEC
-
Set the close-on-exec (
FD_CLOEXEC
) flag on the new file descriptor. See the description of theO_CLOEXEC
flag in open(2) for reasons why this may be useful.
RETURN VALUE
On success, these system calls return a new file
descriptor. On error, −1 is returned, and errno
is set to indicate the error.
